This is a typical Jack Webb movie, with most of his quirks in it. However, the scene near the end where multiple police units are in pursuit of the killer is wonderful and masterfully done, showing what an under-rated director Jack Webb really was. The only police car you see - until the pursuit is over - is 1-K-80 (Friday and Gannon's unmarked unit) racing through the rain in the night. You hear all of the action over the radio in the detective unit, but never see a black and white sliding around a corner, or racing down the road. Just the same, the scene builds tension and you feel the tension of the pursuit, perhaps better than if you actually saw it portrayed. I think it's one of my favorite scenes in any movie I've ever watched.
